PROBLEM: Cytokines have a significant role in the process of embryo implantation, trophoblast growth, and differentiation by modulating the immune and endocrine system. The aim of this study was to investigate the profile of a large set of cytokines in the cervico-vaginal washing of women undergoing IVF, to explore the association of these proteins with a good receptive endometrium. METHOD OF STUDY: A cohort of 155 women scheduled for IVF cycle was recruited. All patients were asymptomatic for genitourinary infections and had been screened for chlamydia, mycoplasma, and other bacterial infections...

PROBLEM: Rupture of fetal membranes is a crucial event at parturition, which is preceded by extensive extracellular matrix (ECM) remodeling. Our recent studies have demonstrated that the human fetal membranes are capable of de novo synthesis of serum amyloid A1 (SAA1), an acute phase protein, and the abundance of SAA1 in the amnion was increased at parturition. However, the exact role of SAA1 in human parturition remains to be established. METHOD OF STUDY: The effects of SAA1 on the abundance of collagenases and lysyl oxidase, the enzyme that cross-links collagens, were investigated in culture primary human amnion fibroblasts and tissue explants with an aim to examine the involvement of SAA1 in the ECM remodeling in the amnion...

PROBLEM: Several studies have reported the increased risk of preterm birth, premature rupture of membranes and low birth weight in patients with recurrent pregnancy loss (RPL). There have been a limited number of large population-based studies examining adverse pregnancy and perinatal outcome after RPL. Multiple-imputed analyses (MIA) adjusting for biases due to missing data is also lacking. METHOD OF STUDY: A nationwide population-based birth cohort study known as the "Japan Environment and Children's Study (JECS)" was conducted by the Ministry of the Environment...

PROBLEM: The influence of fetal sex on immune responses in multifetal pregnancies remains incompletely elucidated. The a2 isoform of vacuolar adenosine triphosphatase (a2V) is expressed on the cell membrane of maternal lymphoid cells and contributes to down regulation of pro-inflammatory immune responses during gestation. The association between fetal sex and a2V expression on peripheral blood mononuclear cells (PBMCs) from mothers with twin gestations was assessed. METHOD OF STUDY: Patients in this prospective study were 93 women with twin pregnancies in their mid second or early third trimester- 27 with two male, 30 with two female and 36 with one male and one female fetus...

PROBLEM: Aberrant expression of HLA-G in various malignancies has been shown to participate in tumor development by suppressing immune regulation within the tumor microenvironment. The detection of HLA-G has reportedly been correlated with certain clinicopathological parameters in several neoplasms. Both the soluble and membranous forms of HLA-G are biologically active, therefore we aimed to evaluate the HLA-G level by Western blot technique. METHOD OF STUDY: The total amount of HLA-G protein was analyzed in the primary tumor in 113 tissue samples derived from patients with endometrial cancer...

PROBLEM: IFN-alpha receptor deficiency (IFNAR-/- ) enhances immunity to Listeria monocytogenes (LM) and Salmonella enterica serovar Typhimurium (ST) in the non-pregnant state by inhibiting pathogen-induced immune cell death. However, the roles of IFNAR signaling in modulating immunity to infection during pregnancy are not well-understood. METHOD OF STUDY: WT and IFNAR-/- mice were infected systemically with LM or ST. Bacterial burden in spleen and individual placentas was enumerated at day 3 post-infection...

PROBLEM: Recently, we demonstrated both in vitro and in vivo that an immunological crosstalk between Day-7 embryo and immune cells exists locally in the uterus in cows. The peripheral immune response to early embryos at Day-7 of pregnancy in cows remains largely unknown. Thus, we aimed to investigate the response of peripheral blood immune cells in the presence of multiple Day-7 embryos in the uterus in donor cows of embryo transfer program. METHOD OF STUDY: Superovulated cows were either inseminated (n=13) at 12-18 h post-estrus or remained without inseminations (n=6)...

PROBLEM: Endometriosis (EM) is a chronic immunoinflammatory disease associated with an abnormal immunotolerant microenvironment. Myeloid-derived suppressor cells (MDSCs) are a heterogeneous population of immature myeloid cells that play a major role in immunosuppression in cancer, inflammation and other diseases. This paper aims to elucidate whether or not MDSCs are involved in regulating this microenvironment in EM and how this regulation occurs. METHOD OF STUDY: Immunochemistry (IHC) and qPCR were conducted to measure CD11b and ARG1 expression in the ectopic endometrium samples from EM patients...

PROBLEM: During pregnancy, the decidual spiral arterioles (SpAs) that supply maternal blood to the placenta undergo a series of changes to optimise the transfer of nutrients and oxygen to the developing foetus. Recent studies have shown that initiation of SpA transformation coincides with decidual leucocyte infiltration. Leucocytes are known to be a source of matrix metalloproteinases (MMPs); however, the complete profile of MMPs expressed by decidual NK cells (dNK) and macrophages has not been characterised...

PROBLEM: Cytokines, mediators of the immune response, are involved in the regulation of female reproductive processes during the estrous cycle and pregnancy. The present study aimed to investigate the effect of selected peroxisome proliferator-activated receptor gamma (PPARγ) ligands on the expression of nuclear factor kappa B (NF-κB) and selected cytokines, such as interleukin (IL)-1β, -4, -6, -8, -10, and the leukemia inhibitory factor, in the porcine endometrium on days 10-12 and 14-16 of the estrous cycle (mid- and late luteal phase, respectively) or pregnancy (maternal recognition of pregnancy and beginning of implantation, respectively)...

In recent years, extended scientific works shed light on the important role played by the endometrium in early pregnancy. This review examines our current knowledge about the delicate balance between microbial and cellular immune agents at endometrial level: All of them might affect endometrial receptivity. In contrast to the classical thinking of human endometrium as a sterile tissue, several recent studies have drawn attention to a resident population of microorganisms, which reaches only a 30% of concordance with those of the cervical-vaginal flora...

PROBLEM: Candida albicans infection induces damage in host cells that results in the activation of cell death pathways such as apoptosis and necrosis. Autophagy acts as a pro-survival mechanism during various infections and has cross talks with apoptosis. The objective of our study was to delineate the effect of autophagy knockdown in human vaginal epithelial cells (VECs) during Candida infection-induced apoptosis. METHOD OF STUDY: We overexpressed wild-type or mutant form of autophagy-related gene 5 (ATG5) in human VECs and determined the levels of autophagy and lysosome marker genes upon C...

PROBLEM: The role of vitamin D (VD) in IVF outcome and immune parameters has not been elucidated well. METHOD OF STUDY: Women undergoing IVF treatment with GnRH agonist (Agonist) and progestin-primed ovarian stimulation (PPOS) protocols were divided into VD lower (VDL, 25(OH)VD ≤20 ng/mL) and VD higher (VDH, 25(OH)VD >20 ng/mL) groups. Follicular fluid (FF) VD level, IVF outcomes, and peripheral blood immunophenotypes by flow cytometry were analyzed. RESULTS: FF VD levels of the whole subjects were positively correlated with peripheral blood VD level (r = 0...

Preeclampsia is a multi-system hypertensive disorder of pregnancy, with significant rates of maternal and neonatal morbidity. It represents a major cause of preterm birth, as definitive treatment demands fetal delivery. Although its pathophysiology is complicated, placental hypoxia and endothelial dysfunction constitute established pathogenetic steps of the disease. Inflammation is considered to be a crucial mediator of preeclampsia process, as an imbalance between TH 1, TH 2, and TH 17 immune responses is observed...

Oxidative stress (OS) plays a role in uterine tissue remodeling during pregnancy and parturition. While p38 MAPK is an OS-response kinase, a precise functional role is unknown. Therefore, we conducted a systematic review of literature on p38 MAPK expression, activation, and function in reproductive tissues throughout pregnancy and parturition, published between January 1980 and August 2017, using four electronic databases (Web of Science, PubMed, Medline, and CoCHRANE). We identified 418 reports; 108 were selected for full-text evaluation and 74 were included in final review...
